so i have plastic pipework through the whole house (domestic) even coming right out the consumer side of the stop tap,the only thing that isnt plastic is the 22mm gas main which is earthed 10mm. now am i right in thinking all i have to x bond is @ the boiler...? ie gas-flow-cold-hot-return. i have earthed the supply side of the water main 10mm which was in 15mm copper. what about the metal sink in the kitchen?
